  • Abstract:
    The objective of this research was to investigate and document practices currently being used by the

    Nebraska Department of Roads (NDOR) districts and other State DOTs to mitigate pavement edge

    drop off. The NDOR has developed (or borrowed) and is currently incorporating into its standard

    practices several procedures that significantly decrease the incidence and magnitude of pavement

    edge-drop off. As these practices become more fully integrated into highway reconstruction projects,

    pavement edge drop off is expected to decrease dramatically. Localized areas of pavement edge drop

    off along paved lanes with bare or vegetated shoulders were noted as posing particular problems for

    NDOR maintenance personnel. Several commercial systems for artificially reinforcing soil beneath

    vegetated or aggregate shoulders were investigated. Suggestions for follow-on research and field

    studies involving various mitigation procedures are included in the recommendations.
